I'm for consistency, Halsin was introduced that way, it's his personality, he doesn't have to be like the others.
That makes me think of Dragon Age, hmm... there was cute Dorian, a lot of girls wanted him, but there was something right? And he is just an example. So you see the developers don't have to do anything.
Your example actually didn't affect the game, but for other reasons, it was already dead.
